This is a note to let you know that I've just added the patch titled nvmem: release the write-protect pin to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 6f57cbd7ce40323eacf542392bfa70ff2cb42c2a Mon Sep 17 00:00:00 2001 From: Khouloud Touil <ktouil@xxxxxxxxxxxx> Date: Tue, 10 Mar 2020 13:22:50 +0000 Subject: nvmem: release the write-protect pin Put the write-protect GPIO descriptor in nvmem_release() so that it can be automatically released when the associated device's reference count drops to 0.
